1 Treatment of [Ir(PPh3)3Cl] with 2-[5-(pyridin-2-yl)-1H-pyrrol-2-yl]pyridine (Hdpp) in refluxing toluene affords an unexpected pyrrole-metalated iridium(III) hydride complex, [Ir(K2C,N-dpp)(H)(Cl)(PPh3)2] (1), via Cpyrrole-H activation, while the presence of the base KOtBu as the deprotonation reagent produces a pyridine-metalated iridium(III) hydride complex, [Ir(K3C,N,N-dpp)(H)(PPh3)2] (2), via Cpyridine-H activation. Iridium protein phosphatase 4 catalytic subunit Homo sapiens
2 Complex 4 is also readily produced by the reaction of [Ir(PPh3)3Cl] and Hdpp in the presence of KOtBu under refluxing methanol or by the reaction of IrCl3 and PPh3 in refluxing 2-ethoxyethanol. Iridium protein phosphatase 4 catalytic subunit Homo sapiens
